This is a common weapon used by Soviet soldiers. It does high damage and has high accuracy, but is bolt-action with a small magazine. This makes it a great long-range weapon, but it is very ineffective at close range. It is not as common as the German bolt-action rifle, the Kar98k, and therefore may be better traded out for the more common weapon of the two, as ammo will only be dropped by the dead friendlies. They both, however, kill in one shot, or three at long range in UO.

It also comes as a sniper variant. It is largely the same as the unscoped version, but it has a scope. In relation to other sniper rifles, it can be more effective, as a stripper clip is used to reload rather than individual bullets.

This weapon is issued for the Soviet team. It is the same in multiplayer as in singleplayer. A very accurate and powerful, but slow-firing weapon, it is best reserved for medium-long range combat, as in singleplayer. It can kill in just one shot, or three in UO at maximum range, making it very ammo-efficient if the player can land all shots.

In Call of Duty 2, this weapon is still a common find amongst the Soviet soldiers. It is still a good medium-long range weapon. It is still loaded by a stripper clip, and still kills in just one shot, but an enemy may survive a shot to a limb. It is still inadvisable to use it in close quarters. It is still harder to find ammo for compared to the Kar98k.

The sniper variant, however, has a slower reload time, as it must be reloaded one bullet at a time, but is the same in all other areas.

This weapon is again issued to the Soviet team. It is roughly the same as its earlier counterparts. It is very powerful, killing in one shot to the head or chest, but two to the limbs. However, its low rate of fire severely limits its close-range effectiveness.

The Mosin-Nagant is usually found in the early Soviet campaign, but is usually abandoned among players for automatic and semi-automatic weapons, though this is entirely dependent on choice. The Gewehr 43, SVT-40, STG-44, MP40, and the PPSh-41 all outclass the Mosin-Nagant in rate of fire. For the most part, the MP40 and PPSh-41 dominate the majority of player's choice in the Soviet Red Army campaign as most combat is close-quarters, and a bolt action rifle is a terrible choice for such combat. Sgt. Reznov was known to use a scoped Mosin-Nagant while attempting to assassinate General Heinrich Amsel. Reznov gives the Mosin-Nagant to Pvt. Petrenko and uses a PPSh-41 onwards due to his hand being injured in combat. His class changes from Sniper to Submachine Gunner. Pvt. Chernov and other troops mainly use the Mosin-Nagant, until later missions where the SVT-40 appears, though Pvt. Chernov still uses the Mosin-Nagant. Though the Mosin-Nagant has a slow rate of fire, it is perfect for clearing certain areas quickly.

It is good to note that all bolt action rifles have the same accuracy, base damage, reload time and range. Accuracy is all dependent upon the user's ability and when aim is steadied if a sniper scope is attached. Bolt action rifles are only different in bolt cycling rate and scope idle sway, although those differences are negligible.

It has a slower rotating bolt mechanism than other bolt actions and lacks the Arisaka's idle sway reduction when crouched. The Mosin-Nagant's scope view moves less than the Arisaka while cycling the bolt. Unscoped, the iron sight consists of a ring around a metal pin prick that is much easier to use than the Springfield's or the Arisaka's. Although the Kar98k's iron sight is clearer than the Mosin-Nagant's, the latter edges the former, in precision. This weapon can kill in one shot from the chest up without Stopping Power, and from the stomach up, with stopping power, or when using a scope.

The dynamic for the whole weapon changes when the player unlocks the Sniper Scope attachment; damage is increased and visibility over range is increased, as well as an increased reload time as the rounds have to be loaded one at a time, and a separate aiming mechanism.

The Mosin-Nagant is an overall good weapon, recommended to be used at further ranges due to its slow rate of fire, low idle sway (with and without scope), and easy to use iron sights. At closer ranges it is recommended to use a bayonet attachment.

Although never found in any of the maps, the Mosin-Nagant can still be obtained in Der Riese and Verrückt through console commands.

Interestingly, a Pack-a-Punched version can be seen in the game's files (see below). It seems to have been cut out at a much later stage compared to the Arisaka (which can also be upgraded through console commands) as it has engravings.

As evident from the Arisaka, the Pack-a-Punched Mosin-Nagant would probably behave in the same way as the Armageddon (Kar98k) and the Eviscerator (Arisaka), albeit with a scope attached. If the game files still exists, it would be possible to obtain through modding.

The Mosin-Nagant is found very few times and only in the British missions as the German standard sniper rifle. It has a five round magazine in both single player and multiplayer; and has a high power, capable of killing with one shot in any part of the body.

The Mosin Nagant only appears in the mission "Project Nova" and is identical to its World at War counterpart apart from its iced over camouflage, darker wood, scope overlay, and firing sound. It can be picked up with or without a Sniper Scope throughout the mission from dead allies. Unlike all other snipers in Black Ops, the scoped version of the Mosin Nagant has the ADS speed from Call of Duty 2 and Modern Warfare 2 with Sleight of Hand Pro, and also features much less idle sway than other sniper rifles.

The Mosin Nagant also appears in the multiplayer emblem editor, under the name "Mosin".
